摘要： There is provided a model that can evaluate properties of viscoelasticity and also rubber elasticity of an elastic material. A correlation equation between stress and strain that is calculated from: a correlation equation between stress, strain, elastic modulus and relaxation time, calculated based on a Maxwell model in which an elastic element and a viscous element are placed in series; and a correlation equation between strain and elastic modulus, including different moduli depending on properties, the correlation equation between stress and strain including different moduli depending on said properties as parameters is output as a stress-strain curve formula. There is one feature in finding a correlation between the strain and the elastic modulus, and this allows a large deformation behavior of an elastic material having properties of both rubber elasticity and viscoelasticity to be expressed with high quantitative characteristics on simulation.
